Image generation using one or more neural networks

ABSTRACT

Apparatuses, systems, and techniques are presented to generate augmented images. In at least one embodiment, one or more neural networks are used to modify one or more first objects in an image based at least in part upon a modification to be made to one or more second objects in the image.

FIELD

At least one embodiment pertains to processing resources used to perform and facilitate artificial intelligence. For example, at least one embodiment pertains to processors or computing systems used to train neural networks according to various novel techniques described herein.

BACKGROUND

Image and video content is predominantly captured or generated using digital imagery. An advantage of digital image or video data is that it can be easier to edit or manipulate than film-based imagery. In many instances, however, editing or manipulating digital image content still requires a significant amount of manual effort to produce results that both satisfy the intended goal and are visually appealing or realistic. For example, various image augmentation techniques are inadequate as they are unable to automatically modify specific objects in images in a constrained fashion, and do not take into account relationships between those objects for consistency.

DETAILED DESCRIPTION

In at least one embodiment, a user may obtain an image 100 that includes a scene or other content of interest, as illustrated in FIG. 1A. In at least one embodiment, this image can correspond to a photo (or frame of video) captured by a physical camera, or an image generated by an image generation process based on a view from a virtual camera. In at least one embodiment, there may be one or more objects contained or represented in this image that a user would like to augment or otherwise modify in this image. In at least one embodiment, this may include one or more objects such as a gun, in this case a rifle 102 that a user, would like to replace with a different type of gun. In at least one embodiment, a user may be able to provide a separate reference image 110, which in this case contains a representation of a handgun 112 that a user would prefer to have contained in this image. In at least one embodiment, a user may be able to specify this object in other ways as well, such as by selecting from a menu or entering into a text field. In at least one embodiment, a process presented herein can identify a type of object in reference image 110, as in this case may correspond to a “gun” or “weapon,” and can identify any occurrences of objects of a “gun” or “weapon” type in input image 100. In at least one embodiment, such a process can then generate an output image 120 as illustrated in FIG. 1B that contains other objects in this scene, while modifying a type of gun represented in this image. In at least one embodiment, such a process can attempt to include a same handgun as was provided in reference image 110, or may include another object of a “handgun” type or sub-type.

In at least one embodiment, such a process could modify just this weapon according to reference image 110. In at least one embodiment, however, this would result in rifle bullets 104 illustrated in FIG. 1A being represented in output image 120 with a handgun, which would may not be realistic as one cannot load rifle bullets into a standard handgun. In at least one embodiment, a process as presented herein can determine relationships between objects in an image, and can make modifications to one or more objects based on those relationships. In at least one embodiment, this can include determining that a rifle object in input image 100 is related to one or more rifle bullet objects, or rifle ammunition object. In at least one embodiment, when a user requests to augment or modify this rifle object to instead represent a handgun object, such a process can determine that, based at least in part upon their relationship, these rifle bullet objects should also be modified. In at least one embodiment, this can result in handgun bullets 124 then being represented along with handgun 122 in generated image 120. In at least one embodiment, if there were other objects determined to be related to rifle 102, such as may include a holster, case, or rack, those objects could be modified for generated image 120 as well for consistency.

In at least one embodiment, a user may not intend to change a type of object represented in an image, but may instead want to modify or augment a state of an object. In at least one embodiment, this may include modifying a state of an object such as a camera stand 132 in an input image 130. In at least one embodiment, this can include “extending” legs of this camera stand 132 as represented. In at least one embodiment, this extending is not merely warping a representation of camera stand 132 to make it appear longer, but this extending is to cause a camera stand to be included that is in an extended state, such as in generated image 140 of FIG. 1D where all three legs of a camera stand 142 are shown to be extended. In at least one embodiment, this involves determining a first state of camera stand 132 in input image 130, then augmenting or modifying that object to be in a second, target state as in generated image 140 of FIG. 1D.

In at least one embodiment, such a process can also identify one or more related objects in input image 130. In at least one embodiment, this can include identifying a logical and/or spatial relationship between camera stand 132 and camera 134. In at least one embodiment, when generating output image 140, a process can identify this relationship between objects, and can modify one or more aspects of camera 134 based on a change in state of camera stand 132. In at least one embodiment, this can include at least determining a proper placement of a camera 144 for camera stand 142 in this new state. In at least one embodiment, this can include a different position in generated image 140 than in input image 130 which is accurate for this new state. In at least one embodiment, this may also include slightly modifying an orientation of this camera based on this new state, such as where a view of this camera might vary slightly based on this new state. In at least one embodiment, a state change could have been to tilt a portion of stand 142 in image 140, which would require a change in orientation of camera 144 to appear realistic. In at least one embodiment, a change in state of a stand may also trigger a change in type of camera displayed. In at least one embodiment, there may be one type of camera appropriate for a stand in a first state, but a second type of camera appropriate for a stand in a second state. In at least one embodiment, such a process can determine to include a representation of a different type of camera 144 in generated image 140. In at least one embodiment, a user may be able to specify, select, or approve such change through a provided or relevant interface, as may provide a preview of generated image 140 with such a representation.

In at least one embodiment, making such modifications may result in an image that is not realistic. In at least one embodiment, this may include two objects in a generated image 140 appearing to occupy a same space, such as where camera 144 how appears to be in front of a top of a tent in this image, while stand 142 is inside this tent. In at least one embodiment, a process can include analysis of generated images to attempt to detect anomalies, inconsistencies, or other potential issues with quality, consistency, or realism of a generated image. In at least one embodiment, this can include detecting that at least two objects in this image now generate an inconsistency or anomaly based on their positional relationships. In at least one embodiment, such a process can then generate at least a second image 150 wherein a modified state of an object, in this case camera stand 152, is modified to a lesser extent to attempt to generate a realistic or consistent image. In at least one embodiment, this change may first be selected or approved by a user. In at least one embodiment, camera stand 152 is illustrated in a less extended state, and camera 154 is positioned appropriately for this state. In at least one embodiment, a determination can be made that there are no positional anomalies in generated image 150, as this camera and stand are all contained within this tent as represented. In at least one embodiment, this generated image 150 could then be provided as an output image for this specified modification. In at least one embodiment, other modifications could have been made as well, such as to adjust a size of this tent (if such adjustment would be realistic), adjust a type of tent, remove this tent, or change to a different camera or stand, among other such options. In at least one embodiment, these selections can be made or approved by a user. In at least one embodiment, a user could specify a change in state by providing an image of an extended camera stand, or entering a change to be made via text, drawing, dragging, or another such input. Various other augmentations can be requested as well, as may relate to compression, expansion, color change, tilting, and packing, among others.

In at least one embodiment, augmenting of these and other such objects may require different portions of other objects to be visible in a generated image, such as where different portions of one or more background objects are now visible as a result of this modification. In at least one embodiment, this process can generate image content for these sections that is consistent for this image or scene. In at least one embodiment, this can involve inpainting, where content (such as colors, patterns, or textures) from a scene or background is used to fill in pixels for one or more areas or regions of an image in such a way that these regions appear, when displayed, as if this content was part of this image as originally captured or generated. In at least one embodiment, if this image is part of an image sequence or a frame of video, and at least some of these portions are visible in other images or frames, then a second generation pass may be used to instead use actual image data instead of generated or inferred image data, with any inferred regions then being updated accordingly.

In at least one embodiment, a system can be provided that performs deep learning based, unsupervised or semi-supervised, multi-element image and video augmentation. In at least one embodiment, an encoder such as a variational autoencoder (VAE) can be trained on reconstruction of images containing a diverse range of objects. In at least one embodiment, an encoder of this VAE can be used to process this input and reference images and learn its feature set. In at least one embodiment, these features can be encoded into a latent space. In at least one embodiment, this latent space can be fed to a generative network, such as a generative adversarial network (GAN), as a constraint during generation of an output image. In at least one embodiment, pixels of an area or region of exclusion can be replaced in a manner that matches, or corresponds in appearance to, at least an immediate surrounding area, portion, or region of this image. In at least one embodiment, this process can be reversible based on a training process utilized. In at least one embodiment, such an approach can provide for multi-object augmentation without manual selection or masking of image content, since an encoder can learn an entire class of objects and/or their relationships, and multiple encoders can be used that are trained on different classes. In at least one embodiment, a single encoder may be used that is trained on multiple classes of objects. In at least one embodiment, implicit mask application can be provided by learning a representation of arbitrary and uncoordinated external objects or patterns from a reference image in an unsupervised manner, and inpainting a source image to first either retain or eliminate this learned representation.

In at least one embodiment, image editing, manipulation, or generation can be performed locally on a client device 202 as illustrated in system architecture 200 of FIG. 2. In at least one embodiment, at least a portion of this functionality may be provided by an image server 220 across at least one network 212. In at least one embodiment, image content to be modified or generated can include image or video content, where individual video frames can be processed and treated as single images. In at least one embodiment, this image content can relate to gaming, virtual reality (VR), or augmented reality (AR) applications. In at least one embodiment, client device 202 may include or comprise a device such as a desktop computer, notebook computer, gaming console, smart phone, tablet computer, VR headset, AR goggles, a wearable computer, a digital camera, or a smart television. In at least one embodiment, an image application 224 executing on image server 220 can initiate an augmentation session associated with a user of client device 202, as may utilize a session manager 226 and user data stored in a user database 236, and can cause image content 234 to be rendered or generated using a rendering engine 228 or other such component, if needed for this type of content or platform, and transmitted to client device 202 using an appropriate transmission manager 222. In at least one embodiment, client device 202 may provide an image to be processed over network 240, and may receive back an edited or newly-generated image from image server 220. In at least one embodiment, an image application 204 on client device 202 may include an image editor 210 with at least some capabilities wherein an image may be augmented or generated on client device 202 without transmission to image server 220. In at least one embodiment, a camera 208 can be used to capture a source image or a reference image, and a display 206 can be used to display a source, reference, or inpainted image, as well as an interface for manipulating images as provided by image application 204. In at least one embodiment, at least one content manager 212, 230 can be used to store and manage source, reference, or generated images. In at least one embodiment, an image application 204 on client device 202 or an application 224 on image server 220 can include an image editor 210, 232 that can perform one or more image editing, augmentation, modification, manipulation, or generation tasks as discussed and suggested herein. In at least one embodiment, a generator can be trained to perform inpainting to fill in, or generate content for areas of a source image that corresponded to removed objects and thus do not have source content in a generated image. In at least one embodiment, this inpainting can involve using features from surrounding regions of a source image to color pixels using colors, patterns, or textures that match or correspond to those regions, such that newly-generated content appears as if it were contained in an original source image.

In at least one embodiment, an image augmentation module 306 can include components as illustrated in architecture 300 of FIG. 3. In at least one embodiment, a source image 302 can be provided as input, where this source image is to be used as a primary source of image content in generating an output augmented image 330. In at least one embodiment, source image will include at least one object, pattern, or element that a user wants to have augmented or modified with image content that matches, blends, or corresponds to other portions of source image 302, such that a generated output image 330 looks like source image 312 was captured with that augmentation or modification present. In at least one embodiment, a secondary reference image 304 can be supplied that will serve as a guide for this augmentation process. In at least one embodiment, a user may be able to specify a type or extent of augmentation through at least one graphical user interface (GIU) or other such interface, such as a command console or application programming interface (API). In at least one embodiment, such a reference image 304 can include a representation of a type of object that is to be augmented from source image 302 when generating output image 330. In at least one embodiment, this reference image will also represent a required augmentation or modification, such as a new state or type of object to be represented. In at least one embodiment, this can cause any object of that object class to be first be removed from source image then replaced with image content that corresponds to this augmentation. In at least one embodiment, a user may be able to set one or more flags or other indicators to cause one or more specified objects of this class to be augmented, or one or more specified objects of this class not to be augmented. In at least one embodiment, a user may provide multiple reference images, either in sequence or in parallel, to cause multiple types of objects to be augmented. In at least one embodiment, “augmenting” an object from source image 302 refers to generating a version of source image 302 (e.g., generated image 330) that includes some image content from source image 302 but at least some different image content for one or more objects of an object class specified by reference image 304, where areas corresponding to augmented objects may also have at least some inpainting performed to fill any gaps and enable one or more augmented objects to blend with, correspond to, or match other remaining image content. In at least one embodiment, related object augmentation can be performed as well as discussed herein.

In at least one embodiment, image augmentation module 306 can utilize one or more neural networks to identify individual objects, and instances of those objects, in input source and reference images. In at least one embodiment, these networks can also determine classes or types of these objects, as well as temporal positions of those objects. In at least one embodiment, object regions, or object masks, can be determined implicitly based at least in part upon features of each identified object. In at least one embodiment, one or more convolutional neural networks (CNNs) can be used to obtain this object information, including one or more three-dimensional CNNs (3D-CNNs) 308 that are able to provide positional information as well as feature and classification information for individual objects, and object instances, in source image 302 and reference image 304 (if provided).

In at least one embodiment, a 3D-CNN 308 can accept as input an image or video frame. In at least one embodiment, this network can identify, select, and filter features for at least one class of object. In at least one embodiment, not every feature determined for every object may be relevant when performing a specific augmentation, such that it may be advantageous to reduce an overall sample space of features via dimension reduction, which can help to eliminate from consideration any features determined to be irrelevant, or at least having less than a determined amount of relevance. In at least one embodiment, this determination can be learned through an unsupervised training process. In at least one embodiment, dimension reduction can also serve as a measure of compression to store representations for use cases that have a large number of features. In at least one embodiment, dimension reduction can be achieved using auto-encoders, or variational auto-encoders. In at least one embodiment, an auto-encoder first encodes a determined feature into a latent space. In at least one embodiment, this feature can then be decoded from this latent space.

In at least one embodiment, this object feature and position information can be provided to an expert manager 310 for encoding. In at least one embodiment, this object feature and position information can also be written to an object list or object file 332. In at least one embodiment, this information can be used along with source image 302 to present indications of specific objects to a user through GUI 318. In at least one embodiment, this can enable a user to make various selections or requests, such as to group related objects, select objects to be augmented (or not augmented), specify different extents or types of augmentation for different identified objects, etc. In at least one embodiment, a highlight, indication, label, or other information can be provided for each recognized object, and in at least some embodiment a user may be able to modify or correct this information. In at least one embodiment, any relevant selection, augmentation, or other information can then be provided for encoding along with object feature and position information. In at least one embodiment, this positional information can help to identify physical relationships between objects, such as where objects are connected, in contact, obscuring each other, or placed on top of each other.

In at least one embodiment, object feature and position information from one or more 3D-CNNs 308 can be provided to a second set of neural networks 320 for determining other information for these objects, such as state or connectedness information. In at least one embodiment, this can include different types of networks for different types of objects or content, such as a recurrent neural network (RNN) for text and a CNN for graphical objects, etc. In at least one embodiment, these models can be selected based upon types or classes of objects for which they were trained. In at least one embodiment, these models can attempt to determine state information for each object recognized in source image 302 and reference image 304. In at least one embodiment, state is recognized for objects other than objects to be modified in case related changes in state should be made to other objects for consistency or accuracy. In at least one embodiment, these models can be trained to recognize various types of state information for specific classes of objects and output that state information for input to an encoder. In at least one embodiment, these models can also assist in determining connectedness. In at least one embodiment, models trained for certain classes can identify objects that are logically related, such as a camera and a camera stand, or a gun and ammunition, in previous examples. In at least one embodiment, this relationship or connectedness information can also be provided for encoding.

In at least one embodiment, information relating to identified objects can be provided for presentation to a user through a GUI 318. In at least one embodiment, a user can then perform various actions, such as to confirm selections, select additional objects, deselect one or more objects, modify a determined object label or state, group objects, indicate object relationships, or request additional augmentations. In at least one embodiment, this information can be provided for encoding along with determined object information, or can be used for another path through these neural networks to update object data determinations. In at least one embodiment, a similar presentation can be provided through GUI 318 after an augmented image is generated, wherein a user may be able to request at least similar changes.

In at least one embodiment, information such as object features, position, selection, grouping, state, and connectedness can then be provided as input to one or more encoders. In at least one embodiment, there may be multiple encoders, such as variational autoencoders 312, used that are each trained for a class of object (specifically or as a set of classes), and selection is made based on classes of objects identified in source image 302 and reference image 304. In at least one embodiment, an encoder can encode feature information for a class of object into a latent space. In at least one embodiment, this latent space can be provided as input to a generative model, such as a generative adversarial network (GAN) 322, to serve as a constraint for generation of output image 330. In at least one embodiment, multiple encoders to encode objects in different classes can include a different variational autoencoder (VAE) 312 for reconstruction of each of a set of object classes. In at least one embodiment, these VAEs can be considered “experts” for specific object classes in a mixture of experts (MoE)-based approach, as may be implemented using an expert manager 310 module, device, system, component, or service. In at least one embodiment, expert manager 310 can comprise or include a gating network or component to determine which expert VAE 312 to use for each identified object for which at least feature information is provided as input.

In at least one embodiment, a gating network of expert manager 310 can determine an appropriate VAE 312 to use for each object. In at least one embodiment, this can include having multiple VAEs encode and recreate a source or reference image, or portion thereof, and select a VAE that produces a best result, or most accurate recreation. In at least one embodiment, this can be achieved using a Mixture-Of-Experts (MoE) model with a feed-forward gating or decision network that assigns experts based on image features detected by that network. In at least one embodiment, these experts can be variational autoencoders (VAEs) tasked at reconstructing this input reference image. In at least one embodiment, a one or more experts is selected based on reconstruction probability. In at least one embodiment, such assignment helps to assign experts depending on object-level features. In at least one embodiment, a first expert model might specialize in objects of a first class, such as vehicles, while a second expert model might specialize in objects of a second class, such as dogs or animals.

In at least one embodiment, features output from these initial networks 308, 320 can undergo transformation into one or more feature vectors of a specified format or schema. In at least one embodiment, a schema such as a JavaScript Object Notation (JSON) schema can be used that stores data as key-value pairs, such as where each object can be a key in a schema and possible interactions can be set as values for that key. In at least one embodiment, determination of an object can enable interactions and relationships to be determined from this schema. In at least one embodiment, data from feature vectors adhering to this schema can be encoded into a latent space. In at least one embodiment, there may be different transformers used for various types of objects that may be identified. In at least one embodiment, each type of input is transformed into a specific type of feature vector, such as a textual feature vector that adheres to a specified schema.

In at least one embodiment, these feature vectors adhering to a common schema can be encoded into a latent space. In at least one embodiment, this encoding can be performed by at least one neural network-based encoder as may be part of, or correspond to, at least one variational autoencoder (VAE) 312. In at least one embodiment, this encoder 310 can be a multi-dimensional state encoder with caching capability. In at least one embodiment, this encoder takes these feature vectors as input and encodes them into a single or common latent space. In at least one embodiment, this VAE 312 can determine whether it is feasible to generate image or video content with such an augmentation. In at least one embodiment, this VAE can be a deep learning model that is trained using unsupervised learning to understand and encode object views. In at least one embodiment, this unsupervised training will not utilize labeled training data, or may utilize some amount of labeled training data if available. In at least one embodiment, VAE 312 will be trained to capture information about this augmentation and encode this information into a latent space. In at least one embodiment, this latent space will represent a basic understanding of an input image, as well as all of these components of that input image. In at least one embodiment, encodings stored in this latent space can also include features or data relating to objects in an input image. In at least one embodiment, there can be multiple levels of VAEs, such as where a first level of VAEs encodes object data to be provided to a generator 322, and a separate level of VAEs is used to encode constraints to use for generating and grooming an augmented image. In at least one embodiment, these second level VAEs can be trained on encoding these schemas in a way that a GAN can understand.

In at least one embodiment, a selected VAE 312 can include an encoder 314, decoder 316, and loss function that are trained or otherwise to be used for a corresponding class of object. In at least one embodiment, selected VAE 312 will determine and encode features of one or more objects into a latent space. In at least one embodiment, VAE 312 may filter out objects of a class of object from this reference image such that only features of a remainder of image information are encoded into that latent space, whereby an augmented version of that object can be inserted into an appropriate location in output image 330. In at least one embodiment, this latent space can be provided as input to a generator 322, such as a GAN, to act as a constraint on generation of output image 330. In at least one embodiment, generator 322 can accept source image 302 as input in addition to this latent space. In at least one embodiment, generator 322 can then generate at least one output image 330 which includes image content from source image 302 with one or more objects augmented as requested or instructed.

In at least one embodiment, augmentation of one or more objects from a source image may result in a generated image that does not appear realistic, as a significant portion of an original source image may have been removed and replaced with inferred image content. In at least one embodiment, an additional layer or step may be utilized where a generated image is edited back towards a source image in order to attempt to improve a realism of a generated image. In at least one embodiment, another network may be utilized that is trained on detecting anomalies or inconsistencies, and can be used as an anomaly detector 324. In at least one embodiment, this anomaly detector 320 can include one or more models that are each trained using images of one or more classes of objects in various orientations, positions, states, and relationships. In at least one embodiment, these networks can include VAE 326, speech models 328, and other such networks. In at least one embodiment, this anomaly detector 324 might determine that something is not right in this image and indicate presence of an anomaly. In at least one embodiment, a 3D-CNN can be used to localize on this anomaly. In at least one embodiment, this 3D-CNN can also be trained with anomaly detection. In at least one embodiment, given an anomaly that was detected, a 3D-CNN can localize this anomaly in this image, and this information can be provided back to GAN 322 to regenerate that image. In at least one embodiment, originally described CNN can be optional in such a situation, such as where this system is able to work out a way to regenerate that image until an image this GAN generates is not anomalous. In at least one embodiment, an anomalous image can be input to a VAE that can evaluate images generated by GAN 322 to determine presence of an anomaly. In at least one embodiment, a GAN may then add objects or modify aspects of this image in order to make this image non-anomalous. In at least one embodiment, a final output from an anomaly correction module can be an image that appears more realistic and may be more authentic, consistent, or accurate to a human eye.

In at least one embodiment, an anomaly detector can reference parameters of one or more objects that were actually changed through this augmentation. In at least one embodiment, this can involve going back to a respective JSON file that was used to groom generation. In at least one embodiment, this JSON file also serves as a reference for changed during image augmentation. In at least one embodiment, a JSON file might indicate that a height of an object was changed. In at least one embodiment, anomaly detector 324 might then determine that there may have been one or more issues with a generated image that resulted from this change in height. In at least one embodiment, this change data can be provided as input to one or more neural networks to attempt to infer augmentation aspects that may have broken as a result of this change. In at least one embodiment, such a network can learn mappings between types of changes and potential anomalies or issues that may result. In at least one embodiment, this network could then output one or more pairs of objects inferred to be causing at least one anomaly to be detected, and can also in at least one embodiment output a type of change that triggered each pair being selected. In at least one embodiment, a camera example in FIG. 1 has a stand being extended which then partially obstructed a view of a tent due to this change in stand height. In at least one embodiment, image augmentation module 306 may then automatically reduce an amount by which this stand is extended and generate a new augmented image to attempt to reduce or eliminate this anomaly. In at least one embodiment, information about these objects and a corresponding change can be provided to a user, such as through GUI 318, whereby a user may be able to suggest or confirm a different change, such as for a 20% reduction in an amount by which this stand is to be extended in an augmented image. In at least one embodiment, a sentence can be generated from these keywords to help a user understand.

In at least one embodiment, if an aspect such as a change in height of an object is determined to be a potential problem with augmentation, then this process can iterate over generation to continually reduce that change in height until there is no longer an unacceptable anomaly in a generated image. In at least one embodiment, an amount of reduction in each iteration can be hard-coded, configurable, or dynamically determined based on factors such as an original amount of change. In at least one embodiment, input parameters might be dynamically changed for each pass and a new image generated. In at least one embodiment, one or more neural networks can be used that also look at intuition parameter deltas. In at least one embodiment, this may include determining relative impact, such as where a change in color is much less likely to lead to an anomaly as a positional change or orientation change. In at least one embodiment, this model may then determine which intuition parameter to adjust, or by how much each of a set of parameters may be adjusted based on their inferred relative impact. In at least one embodiment, such an approach may modify one parameter at a time, starting with a most parameter most likely having impact, or may start with different relative modifications of multiple parameters. In at least one embodiment, such a process can also recursively look at other objects in this image. In at least one embodiment, an autoencoder can generate links between objects, and a generation process can further build a recursive relationship between objects, such as where objects are not positioned close to each other but are still related. In at least one embodiment, this may include two poles used for a volleyball net that may be located a distance apart, but a VAE can determine a connection between these poles to make similar changes in state or appearance, in order to pass a quality test on an augmented image, such to ensure that these poles are not set at different heights. In at least one embodiment, such a model can also determine connectedness. In at least one embodiment, this may include determining that an object such as a volleyball net is not complete (or at least realistic) if it does not also have two poles to which it is connected. In at least one embodiment, these may be considered three separate objects, but can be treated together due at least in part to their determined connectedness. In at least one embodiment, this can be determined as part of a logical relationship as discussed previously. In at least one embodiment, this connectedness can also be encoded into a latent space for constraining generation of an augmented image. In at least one embodiment, recursion can be used to attempt to capture any links that may previously have been missed in augmentation, or that may now be appropriate as a result of an augmentation. In at least one embodiment, this may include determining to augment an ammunition box as a result of a type of ammunition changing, where that ammunition change resulted from a change in weapon type represented in this image. In at least one embodiment, a VAE can be used for these recursive logic and relationship checks.

In at least one embodiment, a process 400 for generating an augmented image can be performed as illustrated in FIG. 4. In at least one embodiment, a source image can be received 402 that includes representations of one or more objects, at least one of which to be augmented. In at least one embodiment, a reference image can also be received that indicates a type of augmentation to be performed, such as by containing a representation of an object with that augmentation. In at least one embodiment, a user or source could instead provide information about this requested augmentation through another mechanism, such as via text or option selection. In at least one embodiment, these images can be analyzed 404 to identify classes of objects represented in these images, as well as features and positions of those objects. In at least one embodiment, this can include differentiating between multiple instances of a same object class. In at least one embodiment, this analysis can be performed using a first set of neural networks trained on objects of at least these classes. In at least one embodiment, this image data can further be analyzed 406 to attempt to determine additional information about these objects, such as state, relatedness, connectedness, or other such information. In at least one embodiment, this can include determining which objects are related in these images, whether physically, logically, or otherwise. In at least one embodiment, this additional information can be inferred using a second set of neural networks trained on at least these classes of objects.

In at least one embodiment, information about these objects can then be encoded 408 into a latent space using one or more encoders. In at least one embodiment, a mixture-of-experts approach can be used to select from among a set of encoders trained for different classes of objects. In at least one embodiment, this source image can be provided 410 as input to a generative network, or other such generator, along with this latent space as a constraint on generation. In at least one embodiment, this generator can generate 412 an image including at least one augmentation for an identified class of object, as well as any object(s) determined to be sufficiently related to which similar or related augmentation should be applied. In at least one embodiment, this generated image can then be analyzed 414 to detect any anomalies, where those anomalies can consist of any of a number of types of anomalies, as may include image artifacts, irregularities, obstructions, intersections, inconsistencies, or unrealism. In at least one embodiment, if it is determined 416 that such an anomaly is present in this augmented image, and in at least one embodiment if this anomaly fails to satisfy at least one quality criterion, such that this anomaly is severe enough to warrant regeneration, then a new image can be generated 420 with one or more modifications to attempt to remove, or at least reduce, that anomaly. In at least one embodiment, there may be various constraints for image generation, some of which are hard constraints and some of which are soft constraints, and a generator can attempt to satisfy all hard constraints and as many soft constraints as is possible, or at least practical. In at least one embodiment, if it is determined that there are no anomalies, or at least no anomalies severe enough to warrant regeneration, then this generated image can be provided 418 as an output augmented image. In at least one embodiment, a user may have an option to then request one or more additional, or alternative, augmentations and have a new image generated. If an augmented image is part of an image series, or a frame of video, then caching may be used for consistency, where features of any previously-generated augmented images of this sequence or video can act as a constraint upon generation of a subsequent image or frame of that sequence or video.

In at least one embodiment, a process 500 for modifying an image can be performed as illustrated in FIG. 5. In at least one embodiment, a first image can be received 502 that includes one or more first objects and one or more second objects. In at least one embodiment, a first modification is performed 504 for one or more objects in this image, as may correspond to one or more augmentations requested by a user. In at least one embodiment, a second modification can be performed 506 for one or more second objects in this image based at least in part upon this first modification, such as where these second objects are determined to be related to these first objects. In at least one embodiment, a semi-supervised object augmentation image can be utilized that can utilize a secondary reference image to determine one or more augmentations to be performed.

FIG. 12A illustrates an exemplary architecture in which a plurality of GPUs 1210-1213 is communicatively coupled to a plurality of multi-core processors 1205-1206 over high-speed links 1240-1243 (e.g., buses, point-to-point interconnects, etc.). In one embodiment, high-speed links 1240-1243 support a communication throughput of 4 GB/s, 30 GB/s, 80 GB/s or higher. Various interconnect protocols may be used including, but not limited to, PCIe 4.0 or 5.0 and NVLink 2.0.

In addition, and in one embodiment, two or more of GPUs 1210-1213 are interconnected over high-speed links 1229-1230, which may be implemented using same or different protocols/links than those used for high-speed links 1240-1243. Similarly, two or more of multi-core processors 1205-1206 may be connected over high speed link 1228 which may be symmetric multi-processor (SMP) buses operating at 20 GB/s, 30 GB/s, 120 GB/s or higher. Alternatively, all communication between various system components shown in FIG. 12A may be accomplished using same protocols/links (e.g., over a common interconnection fabric).

In one embodiment, each multi-core processor 1205-1206 is communicatively coupled to a processor memory 1201-1202, via memory interconnects 1226-1227, respectively, and each GPU 1210-1213 is communicatively coupled to GPU memory 1220-1223 over GPU memory interconnects 1250-1253, respectively. Memory interconnects 1226-1227 and 1250-1253 may utilize same or different memory access technologies. By way of example, and not limitation, processor memories 1201-1202 and GPU memories 1220-1223 may be volatile memories such as dynamic random access memories (DRAMs) (including stacked DRAMs), Graphics DDR SDRAM (GDDR) (e.g., GDDR5, GDDR6), or High Bandwidth Memory (HBM) and/or may be non-volatile memories such as 3D XPoint or Nano-Ram. In one embodiment, some portion of processor memories 1201-1202 may be volatile memory and another portion may be non-volatile memory (e.g., using a two-level memory (2LM) hierarchy).

As described below, although various processors 1205-1206 and GPUs 1210-1213 may be physically coupled to a particular memory 1201-1202, 1220-1223, respectively, a unified memory architecture may be implemented in which a same virtual system address space (also referred to as “effective address” space) is distributed among various physical memories. For example, processor memories 1201-1202 may each comprise 64 GB of system memory address space and GPU memories 1220-1223 may each comprise 32 GB of system memory address space (resulting in a total of 256 GB addressable memory in this example).

FIG. 12B illustrates additional details for an interconnection between a multi-core processor 1207 and a graphics acceleration module 1246 in accordance with one exemplary embodiment. Graphics acceleration module 1246 may include one or more GPU chips integrated on a line card which is coupled to processor 1207 via high-speed link 1240. Alternatively, graphics acceleration module 1246 may be integrated on a same package or chip as processor 1207.

In at least one embodiment, illustrated processor 1207 includes a plurality of cores 1260A-1260D, each with a translation lookaside buffer 1261A-1261D and one or more caches 1262A-1262D. In at least one embodiment, cores 1260A-1260D may include various other components for executing instructions and processing data which are not illustrated. Caches 1262A-1262D may comprise level 1 (L1) and level 2 (L2) caches. In addition, one or more shared caches 1256 may be included in caches 1262A-1262D and shared by sets of cores 1260A-1260D. For example, one embodiment of processor 1207 includes 24 cores, each with its own L1 cache, twelve shared L2 caches, and twelve shared L3 caches. In this embodiment, one or more L2 and L3 caches are shared by two adjacent cores. Processor 1207 and graphics acceleration module 1246 connect with system memory 1214, which may include processor memories 1201-1202 of FIG. 12A.

Coherency is maintained for data and instructions stored in various caches 1262A-1262D, 1256 and system memory 1214 via inter-core communication over a coherence bus 1264. For example, each cache may have cache coherency logic/circuitry associated therewith to communicate to over coherence bus 1264 in response to detected reads or writes to particular cache lines. In one implementation, a cache snooping protocol is implemented over coherence bus 1264 to snoop cache accesses.

In one embodiment, a proxy circuit 1225 communicatively couples graphics acceleration module 1246 to coherence bus 1264, allowing graphics acceleration module 1246 to participate in a cache coherence protocol as a peer of cores 1260A-1260D. In particular, an interface 1235 provides connectivity to proxy circuit 1225 over high-speed link 1240 (e.g., a PCIe bus, NVLink, etc.) and an interface 1237 connects graphics acceleration module 1246 to link 1240.

In one implementation, an accelerator integration circuit 1236 provides cache management, memory access, context management, and interrupt management services on behalf of a plurality of graphics processing engines 1231, 1232, N of graphics acceleration module 1246. Graphics processing engines 1231, 1232, N may each comprise a separate graphics processing unit (GPU). Alternatively, graphics processing engines 1231, 1232, N may comprise different types of graphics processing engines within a GPU such as graphics execution units, media processing engines (e.g., video encoders/decoders), samplers, and blit engines. In at least one embodiment, graphics acceleration module 1246 may be a GPU with a plurality of graphics processing engines 1231-1232, N or graphics processing engines 1231-1232, N may be individual GPUs integrated on a common package, line card, or chip.

In one embodiment, accelerator integration circuit 1236 includes a memory management unit (MMU) 1239 for performing various memory management functions such as virtual-to-physical memory translations (also referred to as effective-to-real memory translations) and memory access protocols for accessing system memory 1214. MMU 1239 may also include a translation lookaside buffer (TLB) (not shown) for caching virtual/effective to physical/real address translations. In one implementation, a cache 1238 stores commands and data for efficient access by graphics processing engines 1231-1232, N. In one embodiment, data stored in cache 1238 and graphics memories 1233-1234, M is kept coherent with core caches 1262A-1262D, 1256, and system memory 1214. As mentioned above, this may be accomplished via proxy circuit 1225 on behalf of cache 1238 and memories 1233-1234, M (e.g., sending updates to cache 1238 related to modifications/accesses of cache lines on processor caches 1262A-1262D, 1256, and receiving updates from cache 1238).

A set of registers 1245 store context data for threads executed by graphics processing engines 1231-1232, N and a context management circuit 1248 manages thread contexts. For example, context management circuit 1248 may perform save and restore operations to save and restore contexts of various threads during contexts switches (e.g., where a first thread is saved and a second thread is stored so that a second thread can be executed by a graphics processing engine). For example, on a context switch, context management circuit 1248 may store current register values to a designated region in memory (e.g., identified by a context pointer). It may then restore register values when returning to a context. In one embodiment, an interrupt management circuit 1247 receives and processes interrupts received from system devices.

In one implementation, virtual/effective addresses from a graphics processing engine 1231 are translated to real/physical addresses in system memory 1214 by MMU 1239. One embodiment of accelerator integration circuit 1236 supports multiple (e.g., 4, 8, 16) graphics accelerator modules 1246 and/or other accelerator devices. Graphics accelerator module 1246 may be dedicated to a single application executed on processor 1207 or may be shared between multiple applications. In one embodiment, a virtualized graphics execution environment is presented in which resources of graphics processing engines 1231-1232, N are shared with multiple applications or virtual machines (VMs). In at least one embodiment, resources may be subdivided into “slices” which are allocated to different VMs and/or applications based on processing requirements and priorities associated with VMs and/or applications.

In at least one embodiment, accelerator integration circuit 1236 performs as a bridge to a system for graphics acceleration module 1246 and provides address translation and system memory cache services. In addition, accelerator integration circuit 1236 may provide virtualization facilities for a host processor to manage virtualization of graphics processing engines 1231-1232, N, interrupts, and memory management.

Because hardware resources of graphics processing engines 1231-1232, N are mapped explicitly to a real address space seen by host processor 1207, any host processor can address these resources directly using an effective address value. One function of accelerator integration circuit 1236, in one embodiment, is physical separation of graphics processing engines 1231-1232, N so that they appear to a system as independent units.

In at least one embodiment, one or more graphics memories 1233-1234, M are coupled to each of graphics processing engines 1231-1232, N, respectively. Graphics memories 1233-1234, M store instructions and data being processed by each of graphics processing engines 1231-1232, N. Graphics memories 1233-1234, M may be volatile memories such as DRAMs (including stacked DRAMs), GDDR memory (e.g., GDDR5, GDDR6), or HBM, and/or may be non-volatile memories such as 3D XPoint or Nano-Ram.

In one embodiment, to reduce data traffic over link 1240, biasing techniques are used to ensure that data stored in graphics memories 1233-1234, M is data which will be used most frequently by graphics processing engines 1231-1232, N and preferably not used by cores 1260A-1260D (at least not frequently). Similarly, a biasing mechanism attempts to keep data needed by cores (and preferably not graphics processing engines 1231-1232, N) within caches 1262A-1262D, 1256 of cores and system memory 1214.

FIG. 12C illustrates another exemplary embodiment in which accelerator integration circuit 1236 is integrated within processor 1207. In at least this embodiment, graphics processing engines 1231-1232, N communicate directly over high-speed link 1240 to accelerator integration circuit 1236 via interface 1237 and interface 1235 (which, again, may be utilize any form of bus or interface protocol). Accelerator integration circuit 1236 may perform same operations as those described with respect to FIG. 12B, but potentially at a higher throughput given its close proximity to coherence bus 1264 and caches 1262A-1262D, 1256. At least one embodiment supports different programming models including a dedicated-process programming model (no graphics acceleration module virtualization) and shared programming models (with virtualization), which may include programming models which are controlled by accelerator integration circuit 1236 and programming models which are controlled by graphics acceleration module 1246.

In at least one embodiment, graphics processing engines 1231-1232, N are dedicated to a single application or process under a single operating system. In at least one embodiment, a single application can funnel other application requests to graphics processing engines 1231-1232, N, providing virtualization within a VM/partition.

In at least one embodiment, graphics processing engines 1231-1232, N, may be shared by multiple VM/application partitions. In at least one embodiment, shared models may use a system hypervisor to virtualize graphics processing engines 1231-1232, N to allow access by each operating system. For single-partition systems without a hypervisor, graphics processing engines 1231-1232, N are owned by an operating system. In at least one embodiment, an operating system can virtualize graphics processing engines 1231-1232, N to provide access to each process or application.

In at least one embodiment, graphics acceleration module 1246 or an individual graphics processing engine 1231-1232, N selects a process element using a process handle. In at least one embodiment, process elements are stored in system memory 1214 and are addressable using an effective address to real address translation techniques described herein. In at least one embodiment, a process handle may be an implementation-specific value provided to a host process when registering its context with graphics processing engine 1231-1232, N (that is, calling system software to add a process element to a process element linked list). In at least one embodiment, a lower 16-bits of a process handle may be an offset of a process element within a process element linked list.

FIG. 12D illustrates an exemplary accelerator integration slice 1290. As used herein, a “slice” comprises a specified portion of processing resources of accelerator integration circuit 1236. Application effective address space 1282 within system memory 1214 stores process elements 1283. In one embodiment, process elements 1283 are stored in response to GPU invocations 1281 from applications 1280 executed on processor 1207. A process element 1283 contains process state for corresponding application 1280. A work descriptor (WD) 1284 contained in process element 1283 can be a single job requested by an application or may contain a pointer to a queue of jobs. In at least one embodiment, WD 1284 is a pointer to a job request queue in an application's address space 1282.

Graphics acceleration module 1246 and/or individual graphics processing engines 1231-1232, N can be shared by all or a subset of processes in a system. In at least one embodiment, an infrastructure for setting up process state and sending a WD 1284 to a graphics acceleration module 1246 to start a job in a virtualized environment may be included.

In at least one embodiment, a dedicated-process programming model is implementation-specific. In this model, a single process owns graphics acceleration module 1246 or an individual graphics processing engine 1231. Because graphics acceleration module 1246 is owned by a single process, a hypervisor initializes accelerator integration circuit 1236 for an owning partition and an operating system initializes accelerator integration circuit 1236 for an owning process when graphics acceleration module 1246 is assigned.

In operation, a WD fetch unit 1291 in accelerator integration slice 1290 fetches next WD 1284 which includes an indication of work to be done by one or more graphics processing engines of graphics acceleration module 1246. Data from WD 1284 may be stored in registers 1245 and used by MMU 1239, interrupt management circuit 1247, and/or context management circuit 1248 as illustrated. For example, one embodiment of MMU 1239 includes segment/page walk circuitry for accessing segment/page tables 1286 within OS virtual address space 1285. Interrupt management circuit 1247 may process interrupt events 1292 received from graphics acceleration module 1246. When performing graphics operations, an effective address 1293 generated by a graphics processing engine 1231-1232, N is translated to a real address by MMU 1239.

In one embodiment, a same set of registers 1245 are duplicated for each graphics processing engine 1231-1232, N and/or graphics acceleration module 1246 and may be initialized by a hypervisor or operating system. Each of these duplicated registers may be included in an accelerator integration slice 1290. Exemplary registers that may be initialized by a hypervisor are shown in Table 1.

TABLE 1 Hypervisor Initialized Registers 1 Slice Control Register 2 Real Address (RA) Scheduled Processes Area Pointer 3 Authority Mask Override Register 4 Interrupt Vector Table Entry Offset 5 Interrupt Vector Table Entry Limit 6 State Register 7 Logical Partition ID 8 Real address (RA) Hypervisor Accelerator Utilization Record Pointer 9 Storage Description Register

Exemplary registers that may be initialized by an operating system are shown in Table 2.

TABLE 2 Operating System Initialized Registers 1 Process and Thread Identification 2 Effective Address (EA) Context Save/Restore Pointer 3 Virtual Address (VA) Accelerator Utilization Record Pointer 4 Virtual Address (VA) Storage Segment Table Pointer 5 Authority Mask 6 Work descriptor

In one embodiment, each WD 1284 is specific to a particular graphics acceleration module 1246 and/or graphics processing engines 1231-1232, N. It contains all information required by a graphics processing engine 1231-1232, N to do work or it can be a pointer to a memory location where an application has set up a command queue of work to be completed.

FIG. 12E illustrates additional details for one exemplary embodiment of a shared model. This embodiment includes a hypervisor real address space 1298 in which a process element list 1299 is stored. Hypervisor real address space 1298 is accessible via a hypervisor 1296 which virtualizes graphics acceleration module engines for operating system 1295.

In at least one embodiment, shared programming models allow for all or a subset of processes from all or a subset of partitions in a system to use a graphics acceleration module 1246. There are two programming models where graphics acceleration module 1246 is shared by multiple processes and partitions: time-sliced shared and graphics-directed shared.

In this model, system hypervisor 1296 owns graphics acceleration module 1246 and makes its function available to all operating systems 1295. For a graphics acceleration module 1246 to support virtualization by system hypervisor 1296, graphics acceleration module 1246 may adhere to the following: 1) An application's job request must be autonomous (that is, state does not need to be maintained between jobs), or graphics acceleration module 1246 must provide a context save and restore mechanism. 2) An application's job request is guaranteed by graphics acceleration module 1246 to complete in a specified amount of time, including any translation faults, or graphics acceleration module 1246 provides an ability to preempt processing of a job. 3) Graphics acceleration module 1246 must be guaranteed fairness between processes when operating in a directed shared programming model.

In at least one embodiment, application 1280 is required to make an operating system 1295 system call with a graphics acceleration module 1246 type, a work descriptor (WD), an authority mask register (AMR) value, and a context save/restore area pointer (CSRP). In at least one embodiment, graphics acceleration module 1246 type describes a targeted acceleration function for a system call. In at least one embodiment, graphics acceleration module 1246 type may be a system-specific value. In at least one embodiment, WD is formatted specifically for graphics acceleration module 1246 and can be in a form of a graphics acceleration module 1246 command, an effective address pointer to a user-defined structure, an effective address pointer to a queue of commands, or any other data structure to describe work to be done by graphics acceleration module 1246. In one embodiment, an AMR value is an AMR state to use for a current process. In at least one embodiment, a value passed to an operating system is similar to an application setting an AMR. If accelerator integration circuit 1236 and graphics acceleration module 1246 implementations do not support a User Authority Mask Override Register (UAMOR), an operating system may apply a current UAMOR value to an AMR value before passing an AMR in a hypervisor call. Hypervisor 1296 may optionally apply a current Authority Mask Override Register (AMOR) value before placing an AMR into process element 1283. In at least one embodiment, CSRP is one of registers 1245 containing an effective address of an area in an application's effective address space 1282 for graphics acceleration module 1246 to save and restore context state. This pointer is optional if no state is required to be saved between jobs or when a job is preempted. In at least one embodiment, context save/restore area may be pinned system memory.

Upon receiving a system call, operating system 1295 may verify that application 1280 has registered and been given authority to use graphics acceleration module 1246. Operating system 1295 then calls hypervisor 1296 with information shown in Table 3.

TABLE 3 OS to Hypervisor Call Parameters 1 A work descriptor (WD) 2 An Authority Mask Register (AMR) value (potentially masked) 3 An effective address (EA) Context Save/Restore Area Pointer (CSRP) 4 A process ID (PID) and optional thread ID (TID) 5 A virtual address (VA) accelerator utilization record pointer (AURP) 6 Virtual address of storage segment table pointer (SSTP) 7 A logical interrupt service number (LISN)

Upon receiving a hypervisor call, hypervisor 1296 verifies that operating system 1295 has registered and been given authority to use graphics acceleration module 1246. Hypervisor 1296 then puts process element 1283 into a process element linked list for a corresponding graphics acceleration module 1246 type. A process element may include information shown in Table 4.

TABLE 4 Process Element Information 1 A work descriptor (WD) 2 An Authority Mask Register (AMR) value (potentially masked). 3 An effective address (EA) Context Save/Restore Area Pointer (CSRP) 4 A process ID (PID) and optional thread ID (TID) 5 A virtual address (VA) accelerator utilization record pointer (AURP) 6 Virtual address of storage segment table pointer (SSTP) 7 A logical interrupt service number (LISN) 8 Interrupt vector table, derived from hypervisor call parameters 9 A state register (SR) value 10 A logical partition ID (LPID) 11 A real address (RA) hypervisor accelerator utilization record pointer 12 Storage Descriptor Register (SDR)

In at least one embodiment, hypervisor initializes a plurality of accelerator integration slice 1290 registers 1245.

As illustrated in FIG. 12F, in at least one embodiment, a unified memory is used, addressable via a common virtual memory address space used to access physical processor memories 1201-1202 and GPU memories 1220-1223. In this implementation, operations executed on GPUs 1210-1213 utilize a same virtual/effective memory address space to access processor memories 1201-1202 and vice versa, thereby simplifying programmability. In one embodiment, a first portion of a virtual/effective address space is allocated to processor memory 1201, a second portion to second processor memory 1202, a third portion to GPU memory 1220, and so on. In at least one embodiment, an entire virtual/effective memory space (sometimes referred to as an effective address space) is thereby distributed across each of processor memories 1201-1202 and GPU memories 1220-1223, allowing any processor or GPU to access any physical memory with a virtual address mapped to that memory.

In one embodiment, bias/coherence management circuitry 1294A-1294E within one or more of MMUs 1239A-1239E ensures cache coherence between caches of one or more host processors (e.g., 1205) and GPUs 1210-1213 and implements biasing techniques indicating physical memories in which certain types of data should be stored. While multiple instances of bias/coherence management circuitry 1294A-1294E are illustrated in FIG. 12F, bias/coherence circuitry may be implemented within an MMU of one or more host processors 1205 and/or within accelerator integration circuit 1236.

One embodiment allows GPU-attached memory 1220-1223 to be mapped as part of system memory, and accessed using shared virtual memory (SVM) technology, but without suffering performance drawbacks associated with full system cache coherence. In at least one embodiment, an ability for GPU-attached memory 1220-1223 to be accessed as system memory without onerous cache coherence overhead provides a beneficial operating environment for GPU offload. This arrangement allows host processor 1205 software to setup operands and access computation results, without overhead of tradition I/O DMA data copies. Such traditional copies involve driver calls, interrupts and memory mapped I/O (MMIO) accesses that are all inefficient relative to simple memory accesses. In at least one embodiment, an ability to access GPU attached memory 1220-1223 without cache coherence overheads can be critical to execution time of an offloaded computation. In cases with substantial streaming write memory traffic, for example, cache coherence overhead can significantly reduce an effective write bandwidth seen by a GPU 1210-1213. In at least one embodiment, efficiency of operand setup, efficiency of results access, and efficiency of GPU computation may play a role in determining effectiveness of a GPU offload.

In at least one embodiment, selection of GPU bias and host processor bias is driven by a bias tracker data structure. A bias table may be used, for example, which may be a page-granular structure (i.e., controlled at a granularity of a memory page) that includes 1 or 2 bits per GPU-attached memory page. In at least one embodiment, a bias table may be implemented in a stolen memory range of one or more GPU-attached memories 1220-1223, with or without a bias cache in GPU 1210-1213 (e.g., to cache frequently/recently used entries of a bias table). Alternatively, an entire bias table may be maintained within a GPU.

In at least one embodiment, a bias table entry associated with each access to GPU-attached memory 1220-1223 is accessed prior to actual access to a GPU memory, causing the following operations. First, local requests from GPU 1210-1213 that find their page in GPU bias are forwarded directly to a corresponding GPU memory 1220-1223. Local requests from a GPU that find their page in host bias are forwarded to processor 1205 (e.g., over a high-speed link as discussed above). In one embodiment, requests from processor 1205 that find a requested page in host processor bias complete a request like a normal memory read. Alternatively, requests directed to a GPU-biased page may be forwarded to GPU 1210-1213. In at least one embodiment, a GPU may then transition a page to a host processor bias if it is not currently using a page. In at least one embodiment, bias state of a page can be changed either by a software-based mechanism, a hardware-assisted software-based mechanism, or, for a limited set of cases, a purely hardware-based mechanism.

One mechanism for changing bias state employs an API call (e.g., OpenCL), which, in turn, calls a GPU's device driver which, in turn, sends a message (or enqueues a command descriptor) to a GPU directing it to change a bias state and, for some transitions, perform a cache flushing operation in a host. In at least one embodiment, cache flushing operation is used for a transition from host processor 1205 bias to GPU bias, but is not for an opposite transition.

In one embodiment, cache coherency is maintained by temporarily rendering GPU-biased pages uncacheable by host processor 1205. To access these pages, processor 1205 may request access from GPU 1210 which may or may not grant access right away. Thus, to reduce communication between processor 1205 and GPU 1210 it is beneficial to ensure that GPU-biased pages are those which are required by a GPU but not host processor 1205 and vice versa.

FIG. 22 is a block diagram of a neuromorphic processor 2200, according to at least one embodiment. In at least one embodiment, neuromorphic processor 2200 may receive one or more inputs from sources external to neuromorphic processor 2200. In at least one embodiment, these inputs may be transmitted to one or more neurons 2202 within neuromorphic processor 2200. In at least one embodiment, neurons 2202 and components thereof may be implemented using circuitry or logic, including one or more arithmetic logic units (ALUs). In at least one embodiment, neuromorphic processor 2200 may include, without limitation, thousands or millions of instances of neurons 2202, but any suitable number of neurons 2202 may be used. In at least one embodiment, each instance of neuron 2202 may include a neuron input 2204 and a neuron output 2206. In at least one embodiment, neurons 2202 may generate outputs that may be transmitted to inputs of other instances of neurons 2202. For example, in at least one embodiment, neuron inputs 2204 and neuron outputs 2206 may be interconnected via synapses 2208.

In at least one embodiment, neurons 2202 and synapses 2208 may be interconnected such that neuromorphic processor 2200 operates to process or analyze information received by neuromorphic processor 2200. In at least one embodiment, neurons 2202 may transmit an output pulse (or “fire” or “spike”) when inputs received through neuron input 2204 exceed a threshold. In at least one embodiment, neurons 2202 may sum or integrate signals received at neuron inputs 2204. For example, in at least one embodiment, neurons 2202 may be implemented as leaky integrate-and-fire neurons, wherein if a sum (referred to as a “membrane potential”) exceeds a threshold value, neuron 2202 may generate an output (or “fire”) using a transfer function such as a sigmoid or threshold function. In at least one embodiment, a leaky integrate-and-fire neuron may sum signals received at neuron inputs 2204 into a membrane potential and may also apply a decay factor (or leak) to reduce a membrane potential. In at least one embodiment, a leaky integrate-and-fire neuron may fire if multiple input signals are received at neuron inputs 2204 rapidly enough to exceed a threshold value (i.e., before a membrane potential decays too low to fire). In at least one embodiment, neurons 2202 may be implemented using circuits or logic that receive inputs, integrate inputs into a membrane potential, and decay a membrane potential. In at least one embodiment, inputs may be averaged, or any other suitable transfer function may be used. Furthermore, in at least one embodiment, neurons 2202 may include, without limitation, comparator circuits or logic that generate an output spike at neuron output 2206 when result of applying a transfer function to neuron input 2204 exceeds a threshold.

In at least one embodiment, once membrane potential is reset to 0, neuron 2202 may resume normal operation after a suitable period of time (or refractory period).

In at least one embodiment, neurons 2202 may be interconnected through synapses 2208. In at least one embodiment, synapses 2208 may operate to transmit signals from an output of a first neuron 2202 to an input of a second neuron 2202. In at least one embodiment, neurons 2202 may transmit information over more than one instance of synapse 2208. In at least one embodiment, one or more instances of neuron output 2206 may be connected, via an instance of synapse 2208, to an instance of neuron input 2204 in same neuron 2202. In at least one embodiment, an instance of neuron 2202 generating an output to be transmitted over an instance of synapse 2208 may be referred to as a “pre-synaptic neuron” with respect to that instance of synapse 2208. In at least one embodiment, an instance of neuron 2202 receiving an input transmitted over an instance of synapse 2208 may be referred to as a “post-synaptic neuron” with respect to that instance of synapse 2208. Because an instance of neuron 2202 may receive inputs from one or more instances of synapse 2208, and may also transmit outputs over one or more instances of synapse 2208, a single instance of neuron 2202 may therefore be both a “pre-synaptic neuron” and “post-synaptic neuron,” with respect to various instances of synapses 2208, in at least one embodiment.

In at least one embodiment, neurons 2202 may be organized into one or more layers. Each instance of neuron 2202 may have one neuron output 2206 that may fan out through one or more synapses 2208 to one or more neuron inputs 2204. In at least one embodiment, neuron outputs 2206 of neurons 2202 in a first layer 2210 may be connected to neuron inputs 2204 of neurons 2202 in a second layer 2212. In at least one embodiment, layer 2210 may be referred to as a “feed-forward layer.” In at least one embodiment, each instance of neuron 2202 in an instance of first layer 2210 may fan out to each instance of neuron 2202 in second layer 2212. In at least one embodiment, first layer 2210 may be referred to as a “fully connected feed-forward layer.” In at least one embodiment, each instance of neuron 2202 in an instance of second layer 2212 may fan out to fewer than all instances of neuron 2202 in a third layer 2214. In at least one embodiment, second layer 2212 may be referred to as a “sparsely connected feed-forward layer.” In at least one embodiment, neurons 2202 in second layer 2212 may fan out to neurons 2202 in multiple other layers, including to neurons 2202 in (same) second layer 2212. In at least one embodiment, second layer 2212 may be referred to as a “recurrent layer.” In at least one embodiment, neuromorphic processor 2200 may include, without limitation, any suitable combination of recurrent layers and feed-forward layers, including, without limitation, both sparsely connected feed-forward layers and fully connected feed-forward layers.

In at least one embodiment, neuromorphic processor 2200 may include, without limitation, a reconfigurable interconnect architecture or dedicated hard wired interconnects to connect synapse 2208 to neurons 2202. In at least one embodiment, neuromorphic processor 2200 may include, without limitation, circuitry or logic that allows synapses to be allocated to different neurons 2202 as needed based on neural network topology and neuron fan-in/out. For example, in at least one embodiment, synapses 2208 may be connected to neurons 2202 using an interconnect fabric, such as network-on-chip, or with dedicated connections. In at least one embodiment, synapse interconnections and components thereof may be implemented using circuitry or logic.

During execution, in at least one embodiment, graphics and media pipelines send thread initiation requests to thread execution logic 2600 via thread spawning and dispatch logic. In at least one embodiment, once a group of geometric objects has been processed and rasterized into pixel data, pixel processor logic (e.g., pixel shader logic, fragment shader logic, etc.) within shader processor 2602 is invoked to further compute output information and cause results to be written to output surfaces (e.g., color buffers, depth buffers, stencil buffers, etc.). In at least one embodiment, a pixel shader or fragment shader calculates values of various vertex attributes that are to be interpolated across a rasterized object. In at least one embodiment, pixel processor logic within shader processor 2602 then executes an application programming interface (API)-supplied pixel or fragment shader program. In at least one embodiment, to execute a shader program, shader processor 2602 dispatches threads to an execution unit (e.g., 2608A) via thread dispatcher 2604. In at least one embodiment, shader processor 2602 uses texture sampling logic in sampler 2610 to access texture data in texture maps stored in memory. In at least one embodiment, arithmetic operations on texture data and input geometry data compute pixel color data for each geometric fragment, or discards one or more pixels from further processing.

In at least one embodiment, training system 3104 may execute training pipelines 3204, similar to those described herein with respect to FIG. 31. In at least one embodiment, where one or more machine learning models are to be used in deployment pipelines 3210 by deployment system 3106, training pipelines 3204 may be used to train or retrain one or more (e.g. pre-trained) models, and/or implement one or more of pre-trained models 3206 (e.g., without a need for retraining or updating). In at least one embodiment, as a result of training pipelines 3204, output model(s) 3116 may be generated. In at least one embodiment, training pipelines 3204 may include any number of processing steps, such as but not limited to imaging data (or other input data) conversion or adaption (e.g., using DICOM adapter 3202A to convert DICOM images to another format suitable for processing by respective machine learning models, such as Neuroimaging Informatics Technology Initiative (NIfTI) format), AI-assisted annotation 3110, labeling or annotating of imaging data 3108 to generate labeled clinic data 3112, model selection from a model registry, model training 3114, training, retraining, or updating models, and/or other processing steps.

In at least one embodiment, one or more of machine learning models may already be trained and ready for deployment so machine learning models may not undergo any processing by training system 3104, and may be implemented by deployment system 3106.

In at least one embodiment, output model(s) 3116 and/or pre-trained model(s) 3206 may include any types of machine learning models depending on implementation or embodiment. In at least one embodiment, and without limitation, machine learning models used by system 3200 may include machine learning model(s) using linear regression, logistic regression, decision trees, support vector machines (SVM), Naïve Bayes, k-nearest neighbor (Knn), K means clustering, random forest, dimensionality reduction algorithms, gradient boosting algorithms, neural networks (e.g., auto-encoders, convolutional, recurrent, perceptrons, Long/Short Term Memory (LSTM), Hopfield, Boltzmann, deep belief, deconvolutional, generative adversarial, liquid state machine, etc.), and/or other types of machine learning models.

In at least one embodiment, training pipelines 3204 may include AI-assisted annotation, as described in more detail herein with respect to at least FIG. 35B. In at least one embodiment, labeled clinic data 3112 (e.g., traditional annotation) may be generated by any number of techniques. In at least one embodiment, labels or other annotations may be generated within a drawing program (e.g., an annotation program), a computer aided design (CAD) program, a labeling program, another type of program suitable for generating annotations or labels for ground truth, and/or may be hand drawn, in some examples. In at least one embodiment, ground truth data may be synthetically produced (e.g., generated from computer models or renderings), real produced (e.g., designed and produced from real-world data), machine-automated (e.g., using feature analysis and learning to extract features from data and then generate labels), human annotated (e.g., labeler, or annotation expert, defines location of labels), and/or a combination thereof. In at least one embodiment, for each instance of imaging data 3108 (or other data type used by machine learning models), there may be corresponding ground truth data generated by training system 3104. In at least one embodiment, AI-assisted annotation may be performed as part of deployment pipelines 3210; either in addition to, or in lieu of AI-assisted annotation included in training pipelines 3204. In at least one embodiment, system 3200 may include a multi-layer platform that may include a software layer (e.g., software 3118) of diagnostic applications (or other application types) that may perform one or more medical imaging and diagnostic functions. In at least one embodiment, system 3200 may be communicatively coupled to (e.g., via encrypted links) PACS server networks of one or more facilities. In at least one embodiment, system 3200 may be configured to access and referenced data (e.g., DICOM data, RIS data, raw data, CIS data, REST compliant data, RPC data, raw data, etc.) from PACS servers (e.g., via a DICOM adapter 3202, or another data type adapter such as RIS, CIS, REST compliant, RPC, raw, etc.) to perform operations, such as training machine learning models, deploying machine learning models, image processing, inferencing, and/or other operations.

In at least one embodiment, a software layer may be implemented as a secure, encrypted, and/or authenticated API through which applications or containers may be invoked (e.g., called) from an external environment(s) (e.g., facility 3102). In at least one embodiment, applications may then call or execute one or more services 3120 for performing compute, AI, or visualization tasks associated with respective applications, and software 3118 and/or services 3120 may leverage hardware 3122 to perform processing tasks in an effective and efficient manner.

In at least one embodiment, deployment system 3106 may execute deployment pipelines 3210. In at least one embodiment, deployment pipelines 3210 may include any number of applications that may be sequentially, non-sequentially, or otherwise applied to imaging data (and/or other data types) generated by imaging devices, sequencing devices, genomics devices, etc.—including AI-assisted annotation, as described above. In at least one embodiment, as described herein, a deployment pipeline 3210 for an individual device may be referred to as a virtual instrument for a device (e.g., a virtual ultrasound instrument, a virtual CT scan instrument, a virtual sequencing instrument, etc.). In at least one embodiment, for a single device, there may be more than one deployment pipeline 3210 depending on information desired from data generated by a device. In at least one embodiment, where detections of anomalies are desired from an MRI machine, there may be a first deployment pipeline 3210, and where image enhancement is desired from output of an MRI machine, there may be a second deployment pipeline 3210.

In at least one embodiment, applications available for deployment pipelines 3210 may include any application that may be used for performing processing tasks on imaging data or other data from devices. In at least one embodiment, different applications may be responsible for image enhancement, segmentation, reconstruction, anomaly detection, object detection, feature detection, treatment planning, dosimetry, beam planning (or other radiation treatment procedures), and/or other analysis, image processing, or inferencing tasks. In at least one embodiment, deployment system 3106 may define constructs for each of applications, such that users of deployment system 3106 (e.g., medical facilities, labs, clinics, etc.) may understand constructs and adapt applications for implementation within their respective facility. In at least one embodiment, an application for image reconstruction may be selected for inclusion in deployment pipeline 3210, but data type generated by an imaging device may be different from a data type used within an application. In at least one embodiment, DICOM adapter 3202B (and/or a DICOM reader) or another data type adapter or reader (e.g., RIS, CIS, REST compliant, RPC, raw, etc.) may be used within deployment pipeline 3210 to convert data to a form useable by an application within deployment system 3106. In at least one embodiment, access to DICOM, RIS, CIS, REST compliant, RPC, raw, and/or other data type libraries may be accumulated and pre-processed, including decoding, extracting, and/or performing any convolutions, color corrections, sharpness, gamma, and/or other augmentations to data. In at least one embodiment, DICOM, RIS, CIS, REST compliant, RPC, and/or raw data may be unordered and a pre-pass may be executed to organize or sort collected data. In at least one embodiment, because various applications may share common image operations, in some embodiments, a data augmentation library (e.g., as one of services 3120) may be used to accelerate these operations. In at least one embodiment, to avoid bottlenecks of conventional processing approaches that rely on CPU processing, parallel computing platform 3230 may be used for GPU acceleration of these processing tasks.

In at least one embodiment, an image reconstruction application may include a processing task that includes use of a machine learning model. In at least one embodiment, a user may desire to use their own machine learning model, or to select a machine learning model from model registry 3124. In at least one embodiment, a user may implement their own machine learning model or select a machine learning model for inclusion in an application for performing a processing task. In at least one embodiment, applications may be selectable and customizable, and by defining constructs of applications, deployment and implementation of applications for a particular user are presented as a more seamless user experience. In at least one embodiment, by leveraging other features of system 3200—such as services 3120 and hardware 3122—deployment pipelines 3210 may be even more user friendly, provide for easier integration, and produce more accurate, efficient, and timely results.

In at least one embodiment, deployment system 3106 may include a user interface 3214 (e.g., a graphical user interface, a web interface, etc.) that may be used to select applications for inclusion in deployment pipeline(s) 3210, arrange applications, modify or change applications or parameters or constructs thereof, use and interact with deployment pipeline(s) 3210 during set-up and/or deployment, and/or to otherwise interact with deployment system 3106. In at least one embodiment, although not illustrated with respect to training system 3104, user interface 3214 (or a different user interface) may be used for selecting models for use in deployment system 3106, for selecting models for training, or retraining, in training system 3104, and/or for otherwise interacting with training system 3104.

In at least one embodiment, pipeline manager 3212 may be used, in addition to an application orchestration system 3228, to manage interaction between applications or containers of deployment pipeline(s) 3210 and services 3120 and/or hardware 3122. In at least one embodiment, pipeline manager 3212 may be configured to facilitate interactions from application to application, from application to service 3120, and/or from application or service to hardware 3122. In at least one embodiment, although illustrated as included in software 3118, this is not intended to be limiting, and in some examples pipeline manager 3212 may be included in services 3120. In at least one embodiment, application orchestration system 3228 (e.g., Kubernetes, DOCKER, etc.) may include a container orchestration system that may group applications into containers as logical units for coordination, management, scaling, and deployment. In at least one embodiment, by associating applications from deployment pipeline(s) 3210 (e.g., a reconstruction application, a segmentation application, etc.) with individual containers, each application may execute in a self-contained environment (e.g., at a kernel level) to increase speed and efficiency.

In at least one embodiment, each application and/or container (or image thereof) may be individually developed, modified, and deployed (e.g., a first user or developer may develop, modify, and deploy a first application and a second user or developer may develop, modify, and deploy a second application separate from a first user or developer), which may allow for focus on, and attention to, a task of a single application and/or container(s) without being hindered by tasks of another application(s) or container(s). In at least one embodiment, communication, and cooperation between different containers or applications may be aided by pipeline manager 3212 and application orchestration system 3228. In at least one embodiment, so long as an expected input and/or output of each container or application is known by a system (e.g., based on constructs of applications or containers), application orchestration system 3228 and/or pipeline manager 3212 may facilitate communication among and between, and sharing of resources among and between, each of applications or containers. In at least one embodiment, because one or more of applications or containers in deployment pipeline(s) 3210 may share same services and resources, application orchestration system 3228 may orchestrate, load balance, and determine sharing of services or resources between and among various applications or containers. In at least one embodiment, a scheduler may be used to track resource requirements of applications or containers, current usage or planned usage of these resources, and resource availability. In at least one embodiment, a scheduler may thus allocate resources to different applications and distribute resources between and among applications in view of requirements and availability of a system. In some examples, a scheduler (and/or other component of application orchestration system 3228) may determine resource availability and distribution based on constraints imposed on a system (e.g., user constraints), such as quality of service (QoS), urgency of need for data outputs (e.g., to determine whether to execute real-time processing or delayed processing), etc.

In at least one embodiment, services 3120 leveraged by and shared by applications or containers in deployment system 3106 may include compute services 3216, AI services 3218, visualization services 3220, and/or other service types. In at least one embodiment, applications may call (e.g., execute) one or more of services 3120 to perform processing operations for an application. In at least one embodiment, compute services 3216 may be leveraged by applications to perform super-computing or other high-performance computing (HPC) tasks. In at least one embodiment, compute service(s) 3216 may be leveraged to perform parallel processing (e.g., using a parallel computing platform 3230) for processing data through one or more of applications and/or one or more tasks of a single application, substantially simultaneously. In at least one embodiment, parallel computing platform 3230 (e.g., NVIDIA's CUDA) may enable general purpose computing on GPUs (GPGPU) (e.g., GPUs 3222). In at least one embodiment, a software layer of parallel computing platform 3230 may provide access to virtual instruction sets and parallel computational elements of GPUs, for execution of compute kernels. In at least one embodiment, parallel computing platform 3230 may include memory and, in some embodiments, a memory may be shared between and among multiple containers, and/or between and among different processing tasks within a single container. In at least one embodiment, inter-process communication (IPC) calls may be generated for multiple containers and/or for multiple processes within a container to use same data from a shared segment of memory of parallel computing platform 3230 (e.g., where multiple different stages of an application or multiple applications are processing same information). In at least one embodiment, rather than making a copy of data and moving data to different locations in memory (e.g., a read/write operation), same data in same location of a memory may be used for any number of processing tasks (e.g., at a same time, at different times, etc.). In at least one embodiment, as data is used to generate new data as a result of processing, this information of a new location of data may be stored and shared between various applications. In at least one embodiment, location of data and a location of updated or modified data may be part of a definition of how a payload is understood within containers.

In at least one embodiment, AI services 3218 may be leveraged to perform inferencing services for executing machine learning model(s) associated with applications (e.g., tasked with performing one or more processing tasks of an application). In at least one embodiment, AI services 3218 may leverage AI system 3224 to execute machine learning model(s) (e.g., neural networks, such as CNNs) for segmentation, reconstruction, object detection, feature detection, classification, and/or other inferencing tasks. In at least one embodiment, applications of deployment pipeline(s) 3210 may use one or more of output models 3116 from training system 3104 and/or other models of applications to perform inference on imaging data (e.g., DICOM data, RIS data, CIS data, REST compliant data, RPC data, raw data, etc.). In at least one embodiment, two or more examples of inferencing using application orchestration system 3228 (e.g., a scheduler) may be available. In at least one embodiment, a first category may include a high priority/low latency path that may achieve higher service level agreements, such as for performing inference on urgent requests during an emergency, or for a radiologist during diagnosis. In at least one embodiment, a second category may include a standard priority path that may be used for requests that may be non-urgent or where analysis may be performed at a later time. In at least one embodiment, application orchestration system 3228 may distribute resources (e.g., services 3120 and/or hardware 3122) based on priority paths for different inferencing tasks of AI services 3218.

In at least one embodiment, shared storage may be mounted to AI services 3218 within system 3200. In at least one embodiment, shared storage may operate as a cache (or other storage device type) and may be used to process inference requests from applications. In at least one embodiment, when an inference request is submitted, a request may be received by a set of API instances of deployment system 3106, and one or more instances may be selected (e.g., for best fit, for load balancing, etc.) to process a request. In at least one embodiment, to process a request, a request may be entered into a database, a machine learning model may be located from model registry 3124 if not already in a cache, a validation step may ensure appropriate machine learning model is loaded into a cache (e.g., shared storage), and/or a copy of a model may be saved to a cache. In at least one embodiment, a scheduler (e.g., of pipeline manager 3212) may be used to launch an application that is referenced in a request if an application is not already running or if there are not enough instances of an application. In at least one embodiment, if an inference server is not already launched to execute a model, an inference server may be launched. Any number of inference servers may be launched per model. In at least one embodiment, in a pull model, in which inference servers are clustered, models may be cached whenever load balancing is advantageous. In at least one embodiment, inference servers may be statically loaded in corresponding, distributed servers.

In at least one embodiment, inferencing may be performed using an inference server that runs in a container. In at least one embodiment, an instance of an inference server may be associated with a model (and optionally a plurality of versions of a model). In at least one embodiment, if an instance of an inference server does not exist when a request to perform inference on a model is received, a new instance may be loaded. In at least one embodiment, when starting an inference server, a model may be passed to an inference server such that a same container may be used to serve different models so long as inference server is running as a different instance.

In at least one embodiment, during application execution, an inference request for a given application may be received, and a container (e.g., hosting an instance of an inference server) may be loaded (if not already), and a start procedure may be called. In at least one embodiment, pre-processing logic in a container may load, decode, and/or perform any additional pre-processing on incoming data (e.g., using a CPU(s) and/or GPU(s)). In at least one embodiment, once data is prepared for inference, a container may perform inference as necessary on data. In at least one embodiment, this may include a single inference call on one image (e.g., a hand X-ray), or may require inference on hundreds of images (e.g., a chest CT). In at least one embodiment, an application may summarize results before completing, which may include, without limitation, a single confidence score, pixel level-segmentation, voxel-level segmentation, generating a visualization, or generating text to summarize findings. In at least one embodiment, different models or applications may be assigned different priorities. For example, some models may have a real-time (TAT<1 min) priority while others may have lower priority (e.g., TAT<10 min). In at least one embodiment, model execution times may be measured from requesting institution or entity and may include partner network traversal time, as well as execution on an inference service.

In at least one embodiment, transfer of requests between services 3120 and inference applications may be hidden behind a software development kit (SDK), and robust transport may be provide through a queue. In at least one embodiment, a request will be placed in a queue via an API for an individual application/tenant ID combination and an SDK will pull a request from a queue and give a request to an application. In at least one embodiment, a name of a queue may be provided in an environment from where an SDK will pick it up. In at least one embodiment, asynchronous communication through a queue may be useful as it may allow any instance of an application to pick up work as it becomes available. Results may be transferred back through a queue, to ensure no data is lost. In at least one embodiment, queues may also provide an ability to segment work, as highest priority work may go to a queue with most instances of an application connected to it, while lowest priority work may go to a queue with a single instance connected to it that processes tasks in an order received. In at least one embodiment, an application may run on a GPU-accelerated instance generated in cloud 3226, and an inference service may perform inferencing on a GPU.

In at least one embodiment, visualization services 3220 may be leveraged to generate visualizations for viewing outputs of applications and/or deployment pipeline(s) 3210. In at least one embodiment, GPUs 3222 may be leveraged by visualization services 3220 to generate visualizations. In at least one embodiment, rendering effects, such as ray-tracing, may be implemented by visualization services 3220 to generate higher quality visualizations. In at least one embodiment, visualizations may include, without limitation, 2D image renderings, 3D volume renderings, 3D volume reconstruction, 2D tomographic slices, virtual reality displays, augmented reality displays, etc. In at least one embodiment, virtualized environments may be used to generate a virtual interactive display or environment (e.g., a virtual environment) for interaction by users of a system (e.g., doctors, nurses, radiologists, etc.). In at least one embodiment, visualization services 3220 may include an internal visualizer, cinematics, and/or other rendering or image processing capabilities or functionality (e.g., ray tracing, rasterization, internal optics, etc.).

In at least one embodiment, hardware 3122 may include GPUs 3222, AI system 3224, cloud 3226, and/or any other hardware used for executing training system 3104 and/or deployment system 3106. In at least one embodiment, GPUs 3222 (e.g., NVIDIA's TESLA and/or QUADRO GPUs) may include any number of GPUs that may be used for executing processing tasks of compute services 3216, AI services 3218, visualization services 3220, other services, and/or any of features or functionality of software 3118. For example, with respect to AI services 3218, GPUs 3222 may be used to perform pre-processing on imaging data (or other data types used by machine learning models), post-processing on outputs of machine learning models, and/or to perform inferencing (e.g., to execute machine learning models). In at least one embodiment, cloud 3226, AI system 3224, and/or other components of system 3200 may use GPUs 3222. In at least one embodiment, cloud 3226 may include a GPU-optimized platform for deep learning tasks. In at least one embodiment, AI system 3224 may use GPUs, and cloud 3226—or at least a portion tasked with deep learning or inferencing—may be executed using one or more AI systems 3224. As such, although hardware 3122 is illustrated as discrete components, this is not intended to be limiting, and any components of hardware 3122 may be combined with, or leveraged by, any other components of hardware 3122.

In at least one embodiment, AI system 3224 may include a purpose-built computing system (e.g., a super-computer or an HPC) configured for inferencing, deep learning, machine learning, and/or other artificial intelligence tasks. In at least one embodiment, AI system 3224 (e.g., NVIDIA's DGX) may include GPU-optimized software (e.g., a software stack) that may be executed using a plurality of GPUs 3222, in addition to CPUs, RAM, storage, and/or other components, features, or functionality. In at least one embodiment, one or more AI systems 3224 may be implemented in cloud 3226 (e.g., in a data center) for performing some or all of AI-based processing tasks of system 3200.

In at least one embodiment, cloud 3226 may include a GPU-accelerated infrastructure (e.g., NVIDIA's NGC) that may provide a GPU-optimized platform for executing processing tasks of system 3200. In at least one embodiment, cloud 3226 may include an AI system(s) 3224 for performing one or more of AI-based tasks of system 3200 (e.g., as a hardware abstraction and scaling platform). In at least one embodiment, cloud 3226 may integrate with application orchestration system 3228 leveraging multiple GPUs to enable seamless scaling and load balancing between and among applications and services 3120. In at least one embodiment, cloud 3226 may tasked with executing at least some of services 3120 of system 3200, including compute services 3216, AI services 3218, and/or visualization services 3220, as described herein. In at least one embodiment, cloud 3226 may perform small and large batch inference (e.g., executing NVIDIA's TENSOR RT), provide an accelerated parallel computing API and platform 3230 (e.g., NVIDIA's CUDA), execute application orchestration system 3228 (e.g., KUBERNETES), provide a graphics rendering API and platform (e.g., for ray-tracing, 2D graphics, 3D graphics, and/or other rendering techniques to produce higher quality cinematics), and/or may provide other functionality for system 3200.

In at least one embodiment, in an effort to preserve patient confidentiality (e.g., where patient data or records are to be used off-premises), cloud 3226 may include a registry—such as a deep learning container registry. In at least one embodiment, a registry may store containers for instantiations of applications that may perform pre-processing, post-processing, or other processing tasks on patient data. In at least one embodiment, cloud 3226 may receive data that includes patient data as well as sensor data in containers, perform requested processing for just sensor data in those containers, and then forward a resultant output and/or visualizations to appropriate parties and/or devices (e.g., on-premises medical devices used for visualization or diagnoses), all without having to extract, store, or otherwise access patient data. In at least one embodiment, confidentiality of patient data is preserved in compliance with HIPAA and/or other data regulations.

FIG. 33A illustrates a data flow diagram for a process 3300 to train, retrain, or update a machine learning model, in accordance with at least one embodiment. In at least one embodiment, process 3300 may be executed using, as a non-limiting example, system 3200 of FIG. 32. In at least one embodiment, process 3300 may leverage services 3120 and/or hardware 3122 of system 3200, as described herein. In at least one embodiment, refined models 3312 generated by process 3300 may be executed by deployment system 3106 for one or more containerized applications in deployment pipelines 3210.

In at least one embodiment, model training 3114 may include retraining or updating an initial model 3304 (e.g., a pre-trained model) using new training data (e.g., new input data, such as customer dataset 3306, and/or new ground truth data associated with input data). In at least one embodiment, to retrain, or update, initial model 3304, output or loss layer(s) of initial model 3304 may be reset, or deleted, and/or replaced with an updated or new output or loss layer(s). In at least one embodiment, initial model 3304 may have previously fine-tuned parameters (e.g., weights and/or biases) that remain from prior training, so training or retraining 3114 may not take as long or require as much processing as training a model from scratch. In at least one embodiment, during model training 3114, by having reset or replaced output or loss layer(s) of initial model 3304, parameters may be updated and re-tuned for a new data set based on loss calculations associated with accuracy of output or loss layer(s) at generating predictions on new, customer dataset 3306 (e.g., image data 3108 of FIG. 31).

In at least one embodiment, pre-trained models 3206 may be stored in a data store, or registry (e.g., model registry 3124 of FIG. 31). In at least one embodiment, pre-trained models 3206 may have been trained, at least in part, at one or more facilities other than a facility executing process 3300. In at least one embodiment, to protect privacy and rights of patients, subjects, or clients of different facilities, pre-trained models 3206 may have been trained, on-premise, using customer or patient data generated on-premise. In at least one embodiment, pre-trained models 3206 may be trained using cloud 3226 and/or other hardware 3122, but confidential, privacy protected patient data may not be transferred to, used by, or accessible to any components of cloud 3226 (or other off premise hardware). In at least one embodiment, where a pre-trained model 3206 is trained at using patient data from more than one facility, pre-trained model 3206 may have been individually trained for each facility prior to being trained on patient or customer data from another facility. In at least one embodiment, such as where a customer or patient data has been released of privacy concerns (e.g., by waiver, for experimental use, etc.), or where a customer or patient data is included in a public data set, a customer or patient data from any number of facilities may be used to train pre-trained model 3206 on-premise and/or off premise, such as in a datacenter or other cloud computing infrastructure.

In at least one embodiment, when selecting applications for use in deployment pipelines 3210, a user may also select machine learning models to be used for specific applications. In at least one embodiment, a user may not have a model for use, so a user may select a pre-trained model 3206 to use with an application. In at least one embodiment, pre-trained model 3206 may not be optimized for generating accurate results on customer dataset 3306 of a facility of a user (e.g., based on patient diversity, demographics, types of medical imaging devices used, etc.). In at least one embodiment, prior to deploying pre-trained model 3206 into deployment pipeline 3210 for use with an application(s), pre-trained model 3206 may be updated, retrained, and/or fine-tuned for use at a respective facility.

In at least one embodiment, a user may select pre-trained model 3206 that is to be updated, retrained, and/or fine-tuned, and pre-trained model 3206 may be referred to as initial model 3304 for training system 3104 within process 3300. In at least one embodiment, customer dataset 3306 (e.g., imaging data, genomics data, sequencing data, or other data types generated by devices at a facility) may be used to perform model training 3114 (which may include, without limitation, transfer learning) on initial model 3304 to generate refined model 3312. In at least one embodiment, ground truth data corresponding to customer dataset 3306 may be generated by training system 3104. In at least one embodiment, ground truth data may be generated, at least in part, by clinicians, scientists, doctors, practitioners, at a facility (e.g., as labeled clinic data 3112 of FIG. 31).

In at least one embodiment, AI-assisted annotation 3110 may be used in some examples to generate ground truth data. In at least one embodiment, AI-assisted annotation 3110 (e.g., implemented using an AI-assisted annotation SDK) may leverage machine learning models (e.g., neural networks) to generate suggested or predicted ground truth data for a customer dataset. In at least one embodiment, user 3310 may use annotation tools within a user interface (a graphical user interface (GUI)) on computing device 3308.

In at least one embodiment, user 3310 may interact with a GUI via computing device 3308 to edit or fine-tune (auto)annotations. In at least one embodiment, a polygon editing feature may be used to move vertices of a polygon to more accurate or fine-tuned locations.

In at least one embodiment, once customer dataset 3306 has associated ground truth data, ground truth data (e.g., from AI-assisted annotation, manual labeling, etc.) may be used by during model training 3114 to generate refined model 3312. In at least one embodiment, customer dataset 3306 may be applied to initial model 3304 any number of times, and ground truth data may be used to update parameters of initial model 3304 until an acceptable level of accuracy is attained for refined model 3312.

FIG. 33B is an example illustration of a client-server architecture 3332 to enhance annotation tools with pre-trained annotation models, in accordance with at least one embodiment. In at least one embodiment, AI-assisted annotation tools 3336 may be instantiated based on a client-server architecture 3332. In at least one embodiment, annotation tools 3336 in imaging applications may aid radiologists, for example, identify organs and abnormalities. In at least one embodiment, imaging applications may include software tools that help user 3310 to identify, as a non-limiting example, a few extreme points on a particular organ of interest in raw images 3334 (e.g., in a 3D MRI or CT scan) and receive auto-annotated results for all 2D slices of a particular organ. In at least one embodiment, results may be stored in a data store as training data 3338 and used as (for example and without limitation) ground truth data for training. In at least one embodiment, when computing device 3308 sends extreme points for AI-assisted annotation 3110, a deep learning model, for example, may receive this data as input and return inference results of a segmented organ or abnormality. In at least one embodiment, pre-instantiated annotation tools, such as AI-Assisted Annotation Tool 3336B in FIG. 33B, may be enhanced by making API calls (e.g., API Call 3344) to a server, such as an Annotation Assistant Server 3340 that may include a set of pre-trained models 3342 stored in an annotation model registry, for example. In at least one embodiment, an annotation model registry may store pre-trained models 3342 (e.g., machine learning models, such as deep learning models) that are pre-trained to perform AI-assisted annotation on a particular organ or abnormality. These models may be further updated by using training pipelines 3204. In at least one embodiment, pre-installed annotation tools may be improved over time as new labeled clinic data 3112 is added.

Other variations are within spirit of present disclosure. Thus, while disclosed techniques are susceptible to various modifications and alternative constructions, certain illustrated embodiments thereof are shown in drawings and have been described above in detail. It should be understood, however, that there is no intention to limit disclosure to specific form or forms disclosed, but on contrary, intention is to cover all modifications, alternative constructions, and equivalents falling within spirit and scope of disclosure, as defined in appended claims.

Use of terms “a” and “an” and “the” and similar referents in context of describing disclosed embodiments (especially in context of following claims) are to be construed to cover both singular and plural, unless otherwise indicated herein or clearly contradicted by context, and not as a definition of a term. Terms “comprising,” “having,” “including,” and “containing” are to be construed as open-ended terms (meaning “including, but not limited to,”) unless otherwise noted. Term “connected,” when unmodified and referring to physical connections, is to be construed as partly or wholly contained within, attached to, or joined together, even if there is something intervening. Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within range, unless otherwise indicated herein and each separate value is incorporated into specification as if it were individually recited herein. Use of term “set” (e.g., “a set of items”) or “subset,” unless otherwise noted or contradicted by context, is to be construed as a nonempty collection comprising one or more members. Further, unless otherwise noted or contradicted by context, term “subset” of a corresponding set does not necessarily denote a proper subset of corresponding set, but subset and corresponding set may be equal.

Conjunctive language, such as phrases of form “at least one of A, B, and C,” or “at least one of A, B and C,” unless specifically stated otherwise or otherwise clearly contradicted by context, is otherwise understood with context as used in general to present that an item, term, etc., may be either A or B or C, or any nonempty subset of set of A and B and C. For instance, in illustrative example of a set having three members, conjunctive phrases “at least one of A, B, and C” and “at least one of A, B and C” refer to any of following sets: {A}, {B}, {C}, {A, B}, {A, C}, {B, C}, {A, B, C}. Thus, such conjunctive language is not generally intended to imply that certain embodiments require at least one of A, at least one of B, and at least one of C each to be present. In addition, unless otherwise noted or contradicted by context, term “plurality” indicates a state of being plural (e.g., “a plurality of items” indicates multiple items). A plurality is at least two items, but can be more when so indicated either explicitly or by context. Further, unless stated otherwise or otherwise clear from context, phrase “based on” means “based at least in part on” and not “based solely on.”

Operations of processes described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. In at least one embodiment, a process such as those processes described herein (or variations and/or combinations thereof) is performed under control of one or more computer systems configured with executable instructions and is implemented as code (e.g., executable instructions, one or more computer programs or one or more applications) executing collectively on one or more processors, by hardware or combinations thereof. In at least one embodiment, code is stored on a computer-readable storage medium, for example, in form of a computer program comprising a plurality of instructions executable by one or more processors. In at least one embodiment, a computer-readable storage medium is a non-transitory computer-readable storage medium that excludes transitory signals (e.g., a propagating transient electric or electromagnetic transmission) but includes non-transitory data storage circuitry (e.g., buffers, cache, and queues) within transceivers of transitory signals. In at least one embodiment, code (e.g., executable code or source code) is stored on a set of one or more non-transitory computer-readable storage media having stored thereon executable instructions (or other memory to store executable instructions) that, when executed (i.e., as a result of being executed) by one or more processors of a computer system, cause computer system to perform operations described herein. A set of non-transitory computer-readable storage media, in at least one embodiment, comprises multiple non-transitory computer-readable storage media and one or more of individual non-transitory storage media of multiple non-transitory computer-readable storage media lack all of code while multiple non-transitory computer-readable storage media collectively store all of code. In at least one embodiment, executable instructions are executed such that different instructions are executed by different processors. For example, a non-transitory computer-readable storage medium stores instructions and a main central processing unit (“CPU”) executes some of instructions while a graphics processing unit (“GPU”) executes other instructions. In at least one embodiment, different components of a computer system have separate processors and different processors execute different subsets of instructions.

Accordingly, in at least one embodiment, computer systems are configured to implement one or more services that singly or collectively perform operations of processes described herein and such computer systems are configured with applicable hardware and/or software that enable performance of operations. Further, a computer system that implements at least one embodiment of present disclosure is a single device and, in another embodiment, is a distributed computer system comprising multiple devices that operate differently such that distributed computer system performs operations described herein and such that a single device does not perform all operations.

Use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended merely to better illuminate embodiments of disclosure and does not pose a limitation on scope of disclosure unless otherwise claimed. No language in specification should be construed as indicating any non-claimed element as essential to practice of disclosure.

All references, including publications, patent applications, and patents, cited herein are hereby incorporated by reference to same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety herein.

In description and claims, terms “coupled” and “connected,” along with their derivatives, may be used. It should be understood that these terms may be not intended as synonyms for each other. Rather, in particular examples, “connected” or “coupled” may be used to indicate that two or more elements are in direct or indirect physical or electrical contact with each other. “Coupled” may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other.

Unless specifically stated otherwise, it may be appreciated that throughout specification terms such as “processing,” “computing,” “calculating,” “determining,” or like, refer to action and/or processes of a computer or computing system, or similar electronic computing device, that manipulate and/or transform data represented as physical, such as electronic, quantities within computing system's registers and/or memories into other data similarly represented as physical quantities within computing system's memories, registers or other such information storage, transmission or display devices.

In a similar manner, term “processor” may refer to any device or portion of a device that processes electronic data from registers and/or memory and transform that electronic data into other electronic data that may be stored in registers and/or memory. As non-limiting examples, “processor” may be a CPU or a GPU. A “computing platform” may comprise one or more processors. As used herein, “software” processes may include, for example, software and/or hardware entities that perform work over time, such as tasks, threads, and intelligent agents. Also, each process may refer to multiple processes, for carrying out instructions in sequence or in parallel, continuously or intermittently. Terms “system” and “method” are used herein interchangeably insofar as system may embody one or more methods and methods may be considered a system.

In present document, references may be made to obtaining, acquiring, receiving, or inputting analog or digital data into a subsystem, computer system, or computer-implemented machine. Obtaining, acquiring, receiving, or inputting analog and digital data can be accomplished in a variety of ways such as by receiving data as a parameter of a function call or a call to an application programming interface. In some implementations, process of obtaining, acquiring, receiving, or inputting analog or digital data can be accomplished by transferring data via a serial or parallel interface. In another implementation, process of obtaining, acquiring, receiving, or inputting analog or digital data can be accomplished by transferring data via a computer network from providing entity to acquiring entity. References may also be made to providing, outputting, transmitting, sending, or presenting analog or digital data. In various examples, process of providing, outputting, transmitting, sending, or presenting analog or digital data can be accomplished by transferring data as an input or output parameter of a function call, a parameter of an application programming interface or interprocess communication mechanism.

Although discussion above sets forth example implementations of described techniques, other architectures may be used to implement described functionality, and are intended to be within scope of this disclosure. Furthermore, although specific distributions of responsibilities are defined above for purposes of discussion, various functions and responsibilities might be distributed and divided in different ways, depending on circumstances.

Furthermore, although subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that subject matter claimed in appended claims is not necessarily limited to specific features or acts described. Rather, specific features and acts are disclosed as exemplary forms of implementing the claims.
